You really should. You've given a bunch of factual claims, but without any sources. Rational people know to check the validity of claims before believing them, but without any sources, they cannot do that, aside from looking them up. But, they shouldn't have to do that - the burden of proof lies with the claim-maker. If you're not going to cite any sources, what's the point of writing all of this? Surely it took some time to write - I'd guess at least 30 minutes, to recall every one of these things - so you might as well include citations. If all of these claims are true, it shouldn't take very long. If you can't find any sources backing your memory up, maybe that means you mis-remembered, or perhaps it's an urban legend.
